Skin tests are a crucial diagnostic tool for confirming allergies and represent the gold standard. These tests are used to confirm inhalant and food allergies, allergies to insect venoms, occupational agents, and medications. The obtained results can help your doctor develop a treatment plan for allergic diseases (avoidance of allergens, medication therapy, or allergen immunotherapy).
The Institute of Virology, Vaccines, and Sera “Torlak” began producing allergenic extracts for various applications in 1965, and in 1983, the first solution for in vivo diagnostics, specifically skin prick testing, was developed. These solutions are packaged in small dark bottles with a dropper and stored in a cool place (5±3°C).
Skin testing is performed on the inner side of the forearm using a lancet and the appropriate allergen extract. The method is nearly entirely safe (the risk of systemic reactions is very low), painless, and brief. A positive test confirms sensitization, but it should always be interpreted in the context of clinical investigations.
Patient preparation:
During the scheduling of this testing, it is necessary to report all medications you regularly take because certain medications may affect the accuracy of the test results (certain medications may enhance or alleviate allergic reactions). It is required that you refrain from using the following medications 5-7 days before skin prick allergy testing:
• medications from the group of antihistamines – medications against allergies such as Aerius, Zyrtec, Claritin, Xyzal, Clarinase, Nixar, Rupafin
• medications that reduce stomach acidity: Cimetidine, Ranitidine
• medications for colds: Rinasek, Fervex
• it is necessary not to use medications from the group of corticosteroids 24 hours before testing: Dexamethasone, Lemod solu, Nyripan, Urbason, Pronison
Conducting the test
Interpretation of the results
Appearance of a rash with a diameter ≥ 3 mm is considered a positive result. False positive tests may occur in patients with urticaria or as a result of using antihistamines, antidepressants, or omalizumab. Negative results and/or suspicious results can be repeated after a few days or undergo in vitro diagnostics (Specific IgE determination).
